B. The sum of complimentary angles is 180°.
C. Two adjacent angles are complementary
(3 points)
A. The sum of the measures of two supplementary angles is 180°
B. The sum of complimentary angles is 180°.
C. Two adjacent angles are complementary.
:: Always true
:: Sometimes true
#Never true
A. The sum of the measures of two supplementary angles is 180°.
:: Always true (supplementary angles by definition add up to 180°)
B. The sum of complementary angles is 180°.
:: Always true (complementary angles by definition add up to 90°, and 90° + 90° = 180°)
C. Two adjacent angles are complementary.
:: Sometimes true (adjacent angles share a common vertex and side, but they may or may not add up to 90°)
